How to know who has the number in the address book with WhatsApp
If you wish know which users among those who are among your contacts have saved your number in the address book, know that you can do this by taking advantage of the functionality of List broadcast di WhatsApp. This feature of the popular messaging platform, in fact, allows you to send messages only to those who have your phone number saved in the phone: this is why it is a particularly effective tool to know with certainty who has saved your number in the address book and who no.
The trick is to send a new broadcast message to two or more contacts: one of the two must be a person who you are sure has saved your number in the address book (perhaps you can use a family member or a trusted friend as a "guinea pig") and the other (or the others, if you want to try multiple contacts) must be someone you are not sure has memorized your number. To know how to proceed on Android and iPhone (WhatsApp Web and WhatsApp Desktop do not allow you to create new broadcasts), all you have to do is continue reading: you will find all the details in the next paragraphs.
Just a small clarification before starting: in order to take advantage of this "trick", it is assumed that both you and the users "suspected" of having saved your number in the address book use WhatsApp, OK? Now we can really get started!

How to know who has the number in the address book without WhatsApp
You wish to know if there is a way to know who has the number in the phonebook without using WhatsApp, maybe because there is a contact who does not use the famous instant messaging app? The answer in this case is ni. There are, in fact, applications that allow (or rather, promise), to find out which contacts have saved their number in the phone book, but often do not work properly or do not work at all.
Some of these apps, such as ME – Simply See (available for Android and iOS), however, allow you to know if one of your contacts has saved our number in the address book only if the latter have installed ME on their device, which is quite unlikely.
Other solutions, still, promise to find out who has saved their number in the address book by registering with them or by paying small amounts of money: I strongly advise you not to resort to such solutions because they almost certainly hide a scam. You risk "giving" your personal information or even your money to complete strangers.How to know who has my number in the phone book
